The 7700 is the basic model of the Dremel Multi-function tools, it is equipped with 7.2 V nickel-cadmium battery and two-stage speed regulation. That's enough for occasional applications in the household and small crafts for carving, cutting or grinding. I have so that the tile joints milled in a shower to freshen up these with white grout color that has worked very well. The ambitious handyman or modellers on the other hand grip befitting a better equipped Dremel as the 8100 or 8200 models, this feature a lithium-ion battery and a stepless speed control.
The Dremel 7700 comes with 30-piece accessory, here, however, each cutting disc supplied is counted, which are only 20 pieces. Otherwise, there are two grinding accessory, two polishing wheels with polishing paste and some Schmirgelaufsätze. Recommended is the chuck, which must be purchased separately but. Herewith the Dremel can be used more versatile than with the pre-assembled collet.
